3D Electron Diffraction -- The Missing Slice for a Complete Nanoscale Analysis of Organic Solar Cells in TEM
Irene Kraus, Mingjian Wu, Stefanie Rechberger +11
Optimizing the performance of organic solar cells (OSCs) hinges on a comprehensive understanding of their nanostructures, yet traditional characterization methods often fall short,…
Gap-free Information Transfer in 4D-STEM via Fusion of Complementary Scattering Channels
Shengbo You, Georgios Varnavides, Sagar Khavnekar +12
Linear phase-contrast scanning transmission electron microscopy (STEM) techniques compatible with high-throughput 4D-STEM acquisition are widely used to enhance phase contrast in w…
Understanding the effect of drying time in process-structure-performance relationships for PM6-Y6 organic solar cells
Marc Steinberger, Maxime Siber, Hans-Joachim Egelhaaf +13
Making solution-cast organic solar cells industrially available generally comes at the cost of significant performance losses compared to device prototypes manufactured under labor…
A Simultaneous Synergistic Protection Mechanism in Hybrid Perovskite-Organic Multi-junctions Enables Long-Term Stable and Efficient Tandem Solar Cells
Chao Liu, Kaicheng Zhang, Xin Zhou +22
Perovskite-organic tandem solar cells (P-O TSCs) hold great promise for next-generation thin-film photovoltaics, with steadily improving power conversion efficiency (PCE). However,…
Correlative and in situ microscopy investigation of phase transformation, crystal growth and degradation of antimony sulfide thin films
Mingjian Wu, Maïssa K. S. Barr, Vanessa M. Koch +8
Antimony sulfide (SbS), a compound of earth-abundant elements with highly anisotropic, quasi-layered crystal structure, triggered growing interest as a solar absorber in ph…
Identification of Polytypism and Their Dislocations in Bilayer MoS2 Using Correlative Transmission Electron Microscopy and Raman Spectroscopy
Xin Zhou, Tobias Dierke, Mingjian Wu +7
Stacking orders and topological defects substantially influence the physical properties of 2D van der Waals (vdW) materials. However, the inherent features of 2D materials challeng…
